In the drawings', see Figs. 1, 2 and '1, the door 40 is shown in itsclosed position, with the lock bolt 88 having its face 90 bearingagainst the vertical face 33 of the locking seat of the keeper 28. Inthis position the outer ,face of themember 46 of the `housing 45abutsagainst the stop' 39, and the door'40 is securely locked in its:closedv The e bolt. The balls 96 andSB at this-closed position Vof thedoor are respectively located intheir cam cavities 14 and 84 asindicated insaidFig. 8.,l

If the lock is to be opened from,l` the outside,

the operator before `leavingtl'ie vehiclepushes,

down the inside adjusting handle |66, to disengage the locking lug |6Ifrom the latch cavity |49 of the arm |46 of the bell crank |44 andthereby the latch heel |41 is disengaged from the latch |09 of theoperating lever |00. This dis'- engagement results by the end |52 of thespring |50 bearing on the arm |45 of the bell crank |44. The operatorthen by means of the outside operating handle ||4 swings down theloperating lever in the direction of the arrow B, which swings the bolt88 in the direction of the arrow C, Fig. l and the locking nose 9| isdisengaged from the keeper 28 and the door 40 can be swung open.

If the operator wishes to remain in the vehicle and be protected fromany one opening the door from the outside, he pulls up the insideadjusting handle |60, to lock the arm |46 to the operating lever |00.

To open the lock with the inside operating handle |80, the latter isswung down, to move the connecting rod 202 in the direction of the arrowM, Fig. 1, and the arm |1| of the bell crank |10 bears on the nose 93.of the bolt 88, to swing the latter in the direction of the arrow C,and the said bolt 88 is swung in position to open the door 40.

Referring to Fig. to swing the bolt 2|0 to open the lock with theoutside operating handle, the operator moves the connecting rod 2.46 'inthe direction of the arrow O, to the position indicated in said Fig. 10to engage said rod with the pin 234 to disengage the locking lever 23|from the lever 225. In this position of the lever 23| the outsideoperating handle ||4 with its square shank 220 can be` turned to openthe lock. When the handle ||4 is turned in the direction of the arrow N,the hook end 256 of the lever 255 coacts with the nose 2|1 of the bolt2|0 and thereby the nose 2|3 of the said bolt 2|0 is disengaged from thekeeper 28. Upon the release of the outside,operating handle ||4 the end244 of the spring 240 swings the lock bolt 2|0 to its locked position.To prevent the opening of the lock with the outside operating handle H4,the connecting rod 246 is moved in the direction opposite to the arrowO, to position the outer end of the elongated opening 249 against thepin 221, whereby the pin 234 is disengaged from the bottom edge of theconnecting rod 246, and the latch end 233 of the lever 23| is lockedwith thel notch 226 of the lever 225.

To open the lock with the inside handle |80 in this modification, theconnecting rod 246 is moved in the direction of the arrow O, and thelever 23| is disengaged from the lever 225,` and the hook lever 255coacting with the nose 2|1 swings the bolt 2|0 to enable the door 40 tobe opened.

When the bolt 2|0 swings up, its lug 2|5 engages the lug 250 of theconnecting rod 246 to disengage the lever. 23|.'from the lever225 andtheoutside handle ||'4 can be operated.

- When the door 401s swung to its closed position, the bolt. 2|0approaches thefkeeper 88, the bottomy 2|4 of the locking nose 2|3 slidesup on theupper inclinednfacerof the keeper 28 and is ultimately seated.in the seat of said keeper havingthe lfaces 33 and 34,. Y,

vBy the coaction of the balls 96 with the cam cavities 14, the saidballs 96 move from the crowns 11 to thepeaks 11a, by virtue of which theouter face of the member 46 of the housing 45 o the lock is positionedtobear against the stop39.

If, the door 40 is in its closed position and Yis swungopen with theinside operating handle |80, the balls 96 and 98 will be positioned withrespect to their cam cavities as shown in Fig. 9.

It will be noted,l see Fig. 1, when the operator opens the door 40 bymeans of the inside operating handle |80 and forgets to manually lowerthe inside adjusting handle |60, to unlock the operating lever |00, insuch a case when the lock bolt 88 is swung to its open position theadjusting nose 93a bears on the heel |62 and lowers the adjusting handle|60 to disengage the lug |6| from the latch cavity |49 of the arm |46 ofthe bell crank |44.
